Porous carbons prepared from biomass by the traditional method of caustic potash etching is common VOCs adsorbents, but their lack of mesopores hinders the mass transfer, limiting their application. Herein, we prepared templateless micro-mesoporous carbon with a high specific surface area by coupling Phanerochaete chrysosporium pretreatment to caustic potash etching, and explored its synergy mechanism. The prepared micro-mesoporous carbon has simultaneously high specific surface areas (2202 m²/g) and proportion of mesopores (71.9%). The promoting effect determined by FTIR and TG-MS implied that P. chrysosporium treatment increases surface oxygen-containing groups (K⁺ combine sites). It led to the simultaneous formation of mesopores without any template. P. chrysosporium pretreated carbonaceous materials exhibited more defects, which resulted in a high specific surface area. Moreover, the samples that were subjected to P. chrysosporium pretreatment and caustic potash etching exhibited higher adsorption capacity (252 mg/g) and higher selectivity for toluene over N₂.

通过传统的苛性钾蚀刻方法从生物质制得的多孔碳是常见的VOCs吸附剂，但它们缺乏中孔会阻碍质量转移，从而限制了其应用。在本文中，我们通过将Phanerochaete chrysosporium预处理与苛性钾蚀刻相结合，制备了具有高比表面积的无模板微中孔碳，并探讨了其协同作用机理。所制备的微中孔碳同时具有高的比表面积（2202m ² / g）和中孔的比例（71.9％）。FTIR和TG-MS确定的促进作用表明金孢假单胞菌处理增加了表面含氧基团（K ⁺合并网站）。它导致没有任何模板的中孔同时形成。金黄色葡萄球菌预处理的碳质材料显示出更多的缺陷，这导致了高的比表面积。而且，经过金黄色葡萄球菌预处理和苛性钾蚀刻的样品相对于N ₂表现出更高的吸附容量（252 mg / g）和更高的甲苯选择性。
